Immersive tubular electric heaters are used for heating liquids, air, etc. The tubular heater components should be stored in a dry place. If the insulation resistance drops below 1 megaohm due to long-term storage, they can be dried in an oven at around 200 ℃ for several hours (or the components can be low-voltage energized for several hours) to restore the insulation resistance.

Instructions for Use

1. The working voltage shall not exceed 1.1 times its rated value. The casing should be effectively grounded.

2. Working environment: humidity not exceeding 95%, no explosive or corrosive gases.

3. The dimension 'C' in the picture must be completely immersed in oil (and checked regularly) to avoid burning out. The heated oil should be non corrosive.

4. Melting solid oils such as asphalt and paraffin should be used with reduced voltage, and after melting, they should be raised to the rated voltage.

5. When carbon deposits are found on the surface of the pipe, they must be removed completely before use to avoid reducing efficiency or even burning out.

6. The outlet end must be kept dry and clean to avoid surface flickering or short circuits.

7. Components should be stored in a dry and ventilated place. If their insulation resistance to ground decreases by 1M Ω after long-term storage, they can be dried in an oven at around 200 ℃ for several hours to recover.
